MILK cooLnR.

Application filed May 31,

To all whom it may concern:-

Be it known that 1, CHARLES acitizen of the United States,

K. Honen, residing at Concord, in thecoun'ty ofEssex and State ofVermont, have invented a new and useful Milk Cooler, of which thefollowing is a specification.

This invention relates to liquid cooling devices, and more particularlyto a device employed for cooling milk or the like, to extract theanimalheat therefrom.

The primary object. of the invention is to provide a device of thischaracter which will discharge the milk or fluid under treatment over acooling element in a fine film, therebyinsuring the liquid contactingwith the surface of the cooler.

A further object of the invention is to provide means for straining theliquid prior to its passage to the cooling element, means being providedto retard the movement of the liquid over the coolingmember.

With the foregoingand other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter de-'scribed and claimed, it being understood that changes in the preciseembodiment-of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings Figure 1 is a side elevational view of acooling device constructed in accordance with the present invention.Figure 2 is a sectional view taken on line 2-2 of Figure l. t

Figure 3 is a vertical sectional view through the cooling device. l

Figure 4 is a sectional view taken on line H of Figure 1.

Figure 5 is a sectional detail view of the cooling member, the figureillustrating a fragment thereof.

Figure 6 is a vertical sectional view taken through the supporting pipeand elements which support the straining member.

Referring to the drawings in detail, the device includes a supporthaving the legs 5 and upper circular member or supporting ring 6 whichhas connection with the legs 5 at the upper ends thereof. The bodyportion of the device comprises a circular member 7 and a tapered lowerportion 8 which terminates in a downwardly extending'cirunder treatment,a layer 1921. Serial No. {173,878.

cular flange 9, there being 10 formed at the base of the member 7 forcontracting witht-he ring 6 to support the body portion of the devicewithin the ring 6. he upper section of the body portion is circular information and indicated by the reference character 11, the samebeingprovided with an extension 12 to be fitted in the member 7 as clearlyshown by Figure 8 of the drawings. A bottom 13 is secured within theupper section 11 and is provided with a depressed portion 1 1 which isapertured to accommodate the pipe 15 which has openings 16 formedtherein, the openings being disposed above the lower wall of thedepressedportion 14: to provide communication between the interior ofthe pipe 15 and interior of the upper section 11. Grooves 17 are formedin the pipe 15 and have their upper ends disposed adjacent to theopenings 16 so that fluid passing through the openings 16 wil1 bedirected through the grooves where the same discharges onto the coolingmember to be hereinafter more fully described;

The straining member comprises a body portion 18 having itslower enddisposed Within the depressed portion 14 and having straining elements19 supported thereby, the straining elements lying in planes above theottom 13 of the upper section -11 so that fluid passing from the uppersection 11 will pass through the straining elements 19 beforethe samepasses to the cooling member. In order to further purify the liquid ofcotton or similar filtering material indicated at 20 may be positionedwithin the depressed portion 14. Formed on the inner wall of the taperedlower portion 8 are the spaced ribs 21 which contact with the .wall ofthe cooling provided a flange member 22'to support the same in spacedrelation with the tapered lower portion 8, thereby providing passagewaysfor the fluid to pass from the device.

This cooling member 22 is hollow and is substantially invertedcone-shaped, to conform with the tapered lower portion 8, and as shown,the upper surface of the cooling member 22 is inclined, as indicated at23,

the same being provided with spirally formed'ribs 24: dividing the uppersurface 23 into a plurality of curved passageways to cause the fluidpassing thereover to take a spiral course in its movement over the 0001-mg member.

.thereover.

A delivering pipe indicated at 24: has one end thereof disposed withinthe cooling member 22, the opposite end thereof being positioned withinthe tank 25, which may be of any size capable of supplying liquid to theinterior of the cooling member 22 for a suflicient period to accomplishthe cooling of a quantity of fluid. A valve member 26 positioned in thepipe at", and controls the passage of cooling fluid from the tank 25 tothe cooling member 22. discharge pipe 27 also has one end thereof incommunication with the cooling member 22 to permitthe cooling fluidwithin the member 22 to circulate.

Positioned within the upper section 11 of the device is a supportingpipe '28 that is provided with grooves 29 adapted to registerwith thegrooves 17 of the pipe v15 when the pipe 28 is rotated in one direction,but when the pipe is movedin a horizontal plane, the grooves 29 aremoved out of registry with the grooves 17 to reduce the flow of fluidthrough the upper section 11, the rotary movement of the pipe beingcontrolled by the pin 30 which is carried thereby and which'moves in arelatively small cut out portion formed in the side wall of the pipe 15.V

In the use of the device, a cooling fluid is positioned in the tank-25the cooling fluid consisting of water iced to a predetermined degree.The fluid under treatment is poured into the upper section 11 of thedevice where the same filters through the lilteringmembers 5:9 and 20and passes through the openings l6 and onto the cooling member 22. Thevalve member 26 is now opened to permit the cooling fluid to pass intothe cooling 'member 22. From the foregoing it will be seen that as thefluid under treatment passes through the passageways formed by thespirally disposed ribs 2st, the low temperature of the member 22 coolsthe fluid passing A can or other receptacle which in the present drawingis indicated by the reference'character 81 is positioned under thedischarge end of the device to receive the cooledfiuid. r

Having thus described the invention, what is claimed as new is 1. Afluid cooling apparatus comprising a body portion having an uppersection and a lower section, a hollow cooling member disposed within thelower section, ribs carried by the lower section and contacting with theouter surface of the cooling member for supporting the cooling member inspaced relation therewith to provide a fluid passageway, spirally uppersurface of the cooling member,means for delivering fluid to the uppersurface of the cooling member and to the passageways, means forfiltering the fluid on its passage to the cooling member, and means fordelivering a cooling fluid to the interior of the cooling member.

2. A fluid cool'n a aratus com rising a body portion having an uppersection and a lower section, a cooling member disposed within the lowersection, a pipe for direct ing cooling fluid to the cooling member, apipe surrounding the first mentioned pipe and having grooves formed'inthe outer surface thereof, means embracing the second mentioned pipe andhaving grooves registering with the second mentioned grooves to providefluid passageways, and said fluid passageways adapted to deliver fluidto be cooled to the cooling member.

'3. it. fluid apparatus comprising a body portion. including an uppersection and a lower section, a cooling member disposed within the lowersection, said upper section having an inclined bottomformed with adepressed portion, a pipe extending through the depressedportiomafiltering member embracing a POFETiOII'Of the pipe, said pipehaving communicating openings and grooves, and said groovesv formingpassageways to allow material to pass to the cooling mem ,ber.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence oftwo witnesses.
